Description

The BH6505K is a 4-channel PWM driver designed for CD and MD player motor and actuator drives. The power MOSFET output stage allows for applications with low power consumption. BH6505K IC also has a charge pump circuit and standard operational amplifier (needed for power MOSFET gate drives), and so supports a wide spectrum of applications.
